-
-So you've got an idea to improve rclone? We love that!
-You'll be glad to hear we've incorporated hundreds of ideas from contributors already.
-
-Probably the latest beta (or stable) release has your feature, so try to update your rclone.
-The update instructions are available at https://rclone.org/commands/rclone_selfupdate/
-
-If it still isn't there, here is a checklist of things to do:
-
-  1. Search the old issues for your idea and +1 or comment on an existing issue if possible.
-  2. Discuss on the forum: https://forum.rclone.org/
-  3. Make a feature request issue (this is the right place!).
-  4. Be prepared to get involved making the feature :-)
-
-Looking forward to your great idea!

+If it is a big feature then make an issue first so it can be discussed.

-To prepare your pull request first press the fork button on [rclone's GitHub
-page](https://github.com/rclone/rclone).
+You'll need a Go environment set up with GOPATH set.  See [the Go
+getting started docs](https://golang.org/doc/install) for more info.

-Then [install Git](https://git-scm.com/downloads) and set your public contribution [name](https://docs.github.com/en/github/getting-started-with-github/setting-your-username-in-git) and [email](https://docs.github.com/en/github/setting-up-and-managing-your-github-user-account/setting-your-commit-email-address#setting-your-commit-email-address-in-git).
+First in your web browser press the fork button on [rclone's Github
+page](https://github.com/ncw/rclone).

-Next open your terminal, change directory to your preferred folder and initialise your local rclone project:
+Now in your terminal

-    git clone https://github.com/rclone/rclone.git
-    cd rclone
+    go get github.com/ncw/rclone
+    cd $GOPATH/src/github.com/ncw/rclone
    git remote rename origin upstream
-      # if you have SSH keys setup in your GitHub account:
    git remote add origin git@github.com:YOURUSER/rclone.git
-      # otherwise:
-    git remote add origin https://github.com/YOURUSER/rclone.git

-Note that most of the terminal commands in the rest of this guide must be executed from the rclone folder created above.
-
-Now [install Go](https://golang.org/doc/install) and verify your installation:
-
-    go version
-
-Great, you can now compile and execute your own version of rclone:
-
-    go build
-    ./rclone version
-
-(Note that you can also replace `go build` with `make`, which will include a
-more accurate version number in the executable as well as enable you to specify
-more build options.) Finally make a branch to add your new feature

+
+Both of these will be run by Travis when you make a pull request but

-
-## Using Git and Github ##
-
-### Committing your changes ###
-
-Follow the guideline for [commit messages](#commit-messages) and then:
-
-    git checkout my-new-feature      # To switch to your branch
-    git status                       # To see the new and changed files
-    git add FILENAME                 # To select FILENAME for the commit
-    git status                       # To verify the changes to be committed
-    git commit                       # To do the commit
-    git log                          # To verify the commit. Use q to quit the log
-
-You can modify the message or changes in the latest commit using:
-
-    git commit --amend
-
-If you amend to commits that have been pushed to GitHub, then you will have to [replace your previously pushed commits](#replacing-your-previously-pushed-commits).
-
-### Replacing your previously pushed commits ###
-
-Note that you are about to rewrite the GitHub history of your branch. It is good practice to involve your collaborators before modifying commits that have been pushed to GitHub.
-
-Your previously pushed commits are replaced by:
-
-    git push --force origin my-new-feature 
-
-### Basing your changes on the latest master ###
-
-To base your changes on the latest version of the [rclone master](https://github.com/rclone/rclone/tree/master) (upstream):
-
-    git checkout master
-    git fetch upstream
-    git merge --ff-only
-    git push origin --follow-tags    # optional update of your fork in GitHub
-    git checkout my-new-feature
-    git rebase master
-
-If you rebase commits that have been pushed to GitHub, then you will have to [replace your previously pushed commits](#replacing-your-previously-pushed-commits).
-
-### Squashing your commits ###
-
-To combine your commits into one commit:
-
-    git log                          # To count the commits to squash, e.g. the last 2
-    git reset --soft HEAD~2          # To undo the 2 latest commits
-    git status                       # To check everything is as expected
-
-If everything is fine, then make the new combined commit:
-
-    git commit                       # To commit the undone commits as one
-
-otherwise, you may roll back using:
-
-    git reflog                       # To check that HEAD{1} is your previous state
-    git reset --soft 'HEAD@{1}'      # To roll back to your previous state
-
-If you squash commits that have been pushed to GitHub, then you will have to [replace your previously pushed commits](#replacing-your-previously-pushed-commits).
-
-Tip: You may like to use `git rebase -i master` if you are experienced or have a more complex situation.
-
-### GitHub Continuous Integration ###
-
-rclone currently uses [GitHub Actions](https://github.com/rclone/rclone/actions) to build and test the project, which should be automatically available for your fork too from the `Actions` tab in your repository.
+If so, then make the changes in the same branch, squash the commits,
+rebase it to master then push it to Github with `--force`.

 ## Testing ##

-### Quick testing ###
-
 rclone's tests are run from the go testing framework, so at the top
 level you can run this to run all the tests.

    go test -v ./...
-
-You can also use `make`, if supported by your platform
-
-    make quicktest
-
-The quicktest is [automatically run by GitHub](#github-continuous-integration) when you push your branch to GitHub.
-
-### Backend testing ###
-
+    
 rclone contains a mixture of unit tests and integration tests.

-the source file in the `Help:` field.
-
-  * Start with the most important information about the option,
-    as a single sentence on a single line.
-    * This text will be used for the command-line flag help.
-    * It will be combined with other information, such as any default value,
-      and the result will look odd if not written as a single sentence.
-    * It should end with a period/full stop character, which will be shown
-      in docs but automatically removed when producing the flag help.
-    * Try to keep it below 80 characters, to reduce text wrapping in the terminal.
-  * More details can be added in a new paragraph, after an empty line (`"\n\n"`).
-    * Like with docs generated from Markdown, a single line break is ignored
-      and two line breaks creates a new paragraph.
-    * This text will be shown to the user in `rclone config`
-      and in the docs (where it will be added by `make backenddocs`,
-      normally run some time before next release).
-  * To create options of enumeration type use the `Examples:` field.
-    * Each example value have their own `Help:` field, but they are treated
-      a bit different than the main option help text. They will be shown
-      as an unordered list, therefore a single line break is enough to
-      create a new list item. Also, for enumeration texts like name of
-      countries, it looks better without an ending period/full stop character.

-## Writing a plugin ##
-
-New features (backends, commands) can also be added "out-of-tree", through Go plugins.
-Changes will be kept in a dynamically loaded file instead of being compiled into the main binary.
-This is useful if you can't merge your changes upstream or don't want to maintain a fork of rclone.
-
-Usage
-
- - Naming
-   - Plugins names must have the pattern `librcloneplugin_KIND_NAME.so`.
-   - `KIND` should be one of `backend`, `command` or `bundle`.
-   - Example: A plugin with backend support for PiFS would be called
-     `librcloneplugin_backend_pifs.so`.
- - Loading
-   - Supported on macOS & Linux as of now. ([Go issue for Windows support](https://github.com/golang/go/issues/19282))
-   - Supported on rclone v1.50 or greater.
-   - All plugins in the folder specified by variable `$RCLONE_PLUGIN_PATH` are loaded.
-   - If this variable doesn't exist, plugin support is disabled.
-   - Plugins must be compiled against the exact version of rclone to work.
-     (The rclone used during building the plugin must be the same as the source of rclone)
-
-Building
-
-To turn your existing additions into a Go plugin, move them to an external repository
-and change the top-level package name to `main`.
-
-Check `rclone --version` and make sure that the plugin's rclone dependency and host Go version match.
-
-Then, run `go build -buildmode=plugin -o PLUGIN_NAME.so .` to build the plugin.

+  * carry forward any patches to vendor stuff
+  * git commit -a -v

-Note that `make update` updates all direct and indirect dependencies
-and there can occasionally be forwards compatibility problems with
-doing that so it may be necessary to roll back dependencies to the
-version specified by `make updatedirect` in order to get rclone to
-build.
-
-## Making a point release
-
-If rclone needs a point release due to some horrendous bug:
-
-Set vars
-
-  * BASE_TAG=v1.XX          # e.g. v1.52
-  * NEW_TAG=${BASE_TAG}.Y   # e.g. v1.52.1
-  * echo $BASE_TAG $NEW_TAG # v1.52 v1.52.1
-
-First make the release branch.  If this is a second point release then
-this will be done already.
-
-  * git branch ${BASE_TAG} ${BASE_TAG}-stable
-  * git co ${BASE_TAG}-stable
-  * make startstable
-
-Now
-
-  * git co ${BASE_TAG}-stable
-  * git cherry-pick any fixes
-  * Do the steps as above
-  * make startstable
-  * git co master
-  * `#` cherry pick the changes to the changelog - check the diff to make sure it is correct
-  * git checkout ${BASE_TAG}-stable docs/content/changelog.md
-  * git commit -a -v -m "Changelog updates from Version ${NEW_TAG}"
-  * git push
-
-## Making a manual build of docker
-
-The rclone docker image should autobuild on via GitHub actions.  If it doesn't
-or needs to be updated then rebuild like this.
-
-See: https://github.com/ilteoood/docker_buildx/issues/19
-See: https://github.com/ilteoood/docker_buildx/blob/master/scripts/install_buildx.sh
-

-docker buildx create --name actions_builder --use
